Plasma Metabonomics of Human Adenovirus-infected Patients with Pneumonia and Upper Respiratory Tract Infection

Objective Human adenovirus(HAdV)infection is common and can develop to serious conditions with high mortality,yet the mechanism of HAdV infection remains unclear.In the present study,the serum metabolite profiles of HAdV-7-infected patients with pneumonia or upper respiratory tract infection(URTI)were explored.Methods In total,35 patients were enrolled in the study following an outbreak of HAdV-7 in the army,of whom 14 had pneumonia and 21 had URTI.Blood samples were collected at the acute stage and at the recovery stage and were analyzed by untargeted metabolomics.Results Over 90% of the differential metabolites identified between the pneumonia patients and URTI patients were lipids and lipid-like molecules,including glycerophospholipids,fatty acyls,and sphingolipids.The metabolic pathways that were significantly enriched were primarily the lipid metabolism pathways,including sphingolipid metabolism,glycerophospholipid metabolism,and linoleic acid metabolism.The sphingolipid metabolism was identified as a significantly differential pathway between the pneumonia patients and URTI patients and between the acute and recovery stages for the pneumonia patients,but not between the acute and recovery stages for the URTI patients.Ceramide and lactosylceramide,involved in sphingolipid metabolism,were significantly higher in the pneumonia patients than in the URTI patients with good discrimination abilities[area under curve(AUC)0.742 and 0.716,respectively;combination AUC 0.801].Conclusion Our results suggested that HAdV modulated lipid metabolism for both the patients with URTI and pneumonia,especially the sphingolipid metabolism involving ceramide and lactosylceramide,which might thus be a potential intervention target in the treatment of HAdV infection.

Prescription practice of antihistamines for acute upper respiratory tract infections in pediatric patients in a local emergency department in Hong Kong

BACKGROUND: Currently there is very limited data in the literature assessing the prevalence of antihistamine prescription, and there is no local prevalence data about the prescription of antihistamine agents among primary practitioner and emergency physicians. The objectives are 1) to report the prevalence of antihistamine prescription for children less than 6 years old with acute upper respiratory infection and 2) to explore the associated factors for the prescription practice.METHODS: This is a cross-sectional study. All consecutive cases of paediatric patients aged 6 or below who presented to the emergency department during a study period of one week from April 1 to July 4, 2009 with diagnosis of acute upper respiratory infection were included. Totally 162 patients were included.RESULTS: Among the 162 cases, 141(87%) patients were prescribed one antihistamine of any group. Sixty(37%) patients were prescribed two or more antihistamines. In multivariate logistic regression model, age was found to be signi? cantly(P<0.001) associated with multiple antihistamine prescription(OR=1.042, 95%CI=1.02 to 1.06). Years of graduation of attending physician for more than 5 years was also a strong predictor of multiple antihistamine prescription(OR=4.654, 95%CI=2.20 to 9.84, P<0.001).CONCLUSION: In the local emergency department, patients' age and the years of graduation from medical school of the attending physician were predictors of multiple antihistamine prescription for acute upper respiratory infections for children aged less than 6.

A Survey of the Experience and Impact of Acute Upper Respiratory Tract Infections on People in Six Countries in the 2011/2012 Common Cold and Flu Season

Introduction: Acute Upper Respiratory Tract Infections (URTIs) are the most common infectious diseases of humankind. While usually mild and self-limiting, they are characterized by a series of simultaneously occurring symptoms/ signs that are sufficiently disruptive to sufferers’ normal activities in which medication is frequently sought. While the literature has many examples of epidemiological studies on these infections, there are few reports on patient experience and impact. This study was designed to investigate these aspects of Common Cold/Flu across six countries. Methods: A minimum of 500 adults aged 18 and older were recruited in each of six countries (Brazil, China, Germany, India, Russia, and the US) using customary survey research sampling techniques. Single 30-minute (online) or 40-minute door-to-door quantitative questionnaires with c. 50 questions were completed with each participant by the global research firm Ipsos. Main Findings: Across countries, incidence and seasonality of infections reported to this study were consistent with published data. There appears to be a need for patient education on the causes and transmission routes of respiratory infections. Getting good quality sleep and being able to continue with daily activities as an infection resolves are significant drivers to therapy. The most common non-prescription therapies reported were multi-ingredient products in line with the simultaneously occurring multi-symptom nature of the condition(s). Conclusions: This study indicated that acute URTIs exert a significant deleterious effect on sufferers. Public health education, possibly best undertaken by Pharmacists has the potential to impact the extent of virus transmission by ensuring that people know the true cause of the infection, how it is transmitted and how best to combat this. The several simultaneously occurring symptoms encourage sufferers to seek multi-ingredient remedies to allow them to continue with normal activities as their infection resolves naturally.

A Meta-Analysis of the Effectiveness of Vitamin C in the Prevention and Treatment of Childhood Upper Respiratory Tract Infections

Background:The effectiveness of vitamin C in the prevention and treatment of pediatric upper respiratory tract infections was evaluated in a meta-analysis.Methods:A total 2,573 children with upper respiratory tract infections were included in the meta-analysis,1,280 of whom received vitamin C and 1,293 who received control medication.The analysis of findings related to the studies included was done through random or fixed effects model to determine whether vitamin C supplementation could stop and control upper respiratory tract infections in children using mean difference(MD)with 95%confidence intervals(CIs).Results:On average,vitamin C-treated children had fewer upper respiratory tract infection bouts,their illness lasted shorter(MD-0.84;95%CI-1.47 to-0.20,P=0.009),and they were less contagious than the control.Conclusions:The number of episodes and illness duration of upper respiratory tract-infected pediatric subjects were considerably reduced in the intervention group(vitamin C)compared to the control.Due to the small sample size in four of 11 studies and the limited number of studies included for comparison,the outcomes should be carefully examined.

Antibiotic prescribing patterns for upper respiratory tract infections in rural Western China

Objective To explore the prescribing patterns of outpatients receiving antibiotics for upper respiratory tract infections(URTIs)in rural Western China and to identify the correlation in terms of doctors and patients characteristics.Methods Totally 7 678 prescriptions for URTIs were collected from 680 primary health village clinics of 40 counties across 10 provinces of Western China.Two outcome variables were used in the analysis:the occurrence of prescribing at least one antibiotic drug for an URTI and the occurrence of prescribing two or more antibiotics for an URTI.GEE logistic regression models were used to examine the socioeconomic and demographic determinants of the above two outcome variables.Results The percentage of prescribing at least one antibiotic for URTIs was 48.6% while the percentage of prescribing antibiotic combination(two or more antibiotics)was 4.6%.The two measurements of antibiotic utilization differed remarkably among the 10 provinces.Patients diagnosed with tonsillitis and faucitis had higher odds(OR=8.86 for tonsillitis and OR=4.64 for faucitis)of antibiotic prescription than patients with other diagnosis of URTIs.Patients with tonsillitis and faucitis also had higher odds(OR=3.82 for tonsillitis and OR=2.71 for faucitis)of multiple antibiotic prescription than those with other diagnosis of URTIs.The number of drugs per prescription and injection in prescriptions were also significant predictors of antibiotic and multiple antibiotic utilization for URTIs.Conclusion It is concluded that the percentage of antibiotic prescription for URTIs is higher in rural Western China than in most of other countries with available data and that prescriptions of antibiotics for URTIs are associated with residence regions of patients,URTI diagnosis and background information on drug prescription.

Qingkailing injection for the treatment of acute upper respiratory infection in children: a systematic review and meta-analysis

Objective:To systematically evaluate the clinical efficacy and safety of Qingkailing (QKL) injection for pediatric acute upper respiratory infection (AURI).Methods:We searched for randomized controlled trials (RCTs) of pediatric AURI treated by QKL and western medicine (WM) in the China National Knowledge Infrastructure Database,China Science and Technology Journal Database,Wanfang,Chinese Biomedical Literature Database,PubMed and Cochrane Library from inception to August,2016.Two reviewers independently retrieved the RCTs and extracted information.The Cochrane Collaboration Risk of Bias Assessment Tool was used to evaluate the methodological quality of RCTs.The data were meta-analyzed by RevMan 5.3 software.Results:Ultimately,21 RCTs that involved 2364 participants were included,and the quality of RCTs was generally poor.According to the meta-analysis,the combined use of QKL and WM for treating AURI can be effective,with a higher total effective rate,less defervescence time and less recovery time of tonsil and throat inflammation.Twenty-five adverse drug reactions (ADRs) were reported in three RCTs,but there were no serious ADRs.Conclusion:The combination of QKL and WM for treating pediatric AURI can result in better effects,but no definitive conclusions can be made regarding its safety.More rigorous RCTs are needed to support the clinical application of QKL.

Objective:To explore the efficacy of Lianhua Qingwen Capsule(莲花清瘟胶囊)on upper respiratory tract infection,to understand the impact of Lianhua Qingwen Capsule(莲花清瘟胶囊)on the treatment outcome of upper respiratory tract infection,and provide reference for rational clinical drug use.Methods:The HIS database based on 18 large third-grade class-A hospitals was selected to match 1:1 for upper respiratory tract infection patients using and without Lianhua Qingwen Capsule(莲花清瘟胶囊)according to certain standards.The recombination of treatment outcome as"recovery"and"improvement"in the database was defined as effective treatment,"ineffectiveness","death"and"other"as ineffectivetreatment populations,and the effectiveness of treatment outcomes in the remerged 2 groups was compared by propensity score method.Results:After matching,454 cases were in both the patients treated by(experimental group)and without(control group)Lianhua Qingwen Capsule(莲花清瘟胶囊).Analysis was performed by three Logistic regression methods,all showing regression coefficients greater than 0 and statistically significant differences(P<0.05).Conclusion:Patients with upper respiratory tract infection treated by Lianhua Qingwen Capsule(莲花清瘟胶囊)are more effective than that without Lianhua Qingwen Capsule(莲花清瘟胶囊),it can improve the clinical efficacy of patients with upper respiratory tract infection。

Impact of Training of Dispensers on Case Management of Acute Respiratory Tract Infections at Community Pharmacies in Pakistan

Purpose: To evaluate the impact of training of dispensers on the process of case management of ARI at community pharmacies in context to history taking and provision of advice working at community pharmacies in Islamabad, Pakistan. Method: A randomized, controlled, blinded intervention study was designed and implemented. Before the implementation of intervention, a baseline study was performed to assess the process of case management for ARI at community pharmacies. The study population included all community pharmacy outlets in Islamabad. After data collection, data was analyzed. The result of the study revealed that the overall process of disease management of ARI at community pharmacies in Pakistan is not satisfactory. Pharmacies of Islamabad which were visited in pre intervention phase (118) were divided into two geographical regions A (intervention) and B (control). From which thirty pharmacies were selected randomly from each region. The targeted group of the interventions was drug sellers. Keeping in view the results of the base line study an educational intervention was designed to improve the case management of ARI at community pharmacies in Pakistan. Results: No significant difference (p ≤ 0.05) was seen in the process of history taking and advice provision in case of ARI management at community pharmacies between pre and post control groups. On the other hand significant difference in the process of history taking and provision of advice for ARI was observed in the intervention group before and after training. Conclusion: The study has highlighted that improvements in the current dispensing practices at community pharmacies are possible through appropriate educational interventions. The dispensers have the potential to provide fast and low cost healthcare to the masses in the country where the presence of doctors and qualified pharmacist is low;to date they are an untapped and underutilized source in the country.

Effect of gastrointestinal heat retention syndrome on gut microbiota in children with upper respiratory tract infection and lung-heat syndrome

Objective:Gastrointestinal heat retention syndrome(GHRS)is associated with lung-heat syndrome and is related to recurrent respiratory infection.Upper respiratory tract infection(URTI)lung heat syndrome is common in children.The study will explore the effect of GHRS on the structure and function of gut microbiota in children with URTI lung-heat syndrome.Methods:Participants were divided into both groups using the self-developed URTI scale and the“GHRS Diagnostic Scale$Pediatric Part”:GHRS-positive children(LS group)and GHRS-negative children(L group).General information,clinical symptoms,and stool were collected.We used 16S rRNA amplicon sequencing technology to determine the gene sequence of the V3eV4 region in feces and measure the gut microbiota of the both groups at the genus level.Results:A total of 23 children were included in the both groups.There were 12 cases in the LS group and 11 cases in the L group.There was no statistical difference between the both groups in age,gender,height,weight,and body mass index.The effective sequences shared by the both groups accounted for 85.66%of the total.In the gut microbiota,there was no difference in the a diversity and the b diversity between the both groups.Compared with the L group,the LS group had a significant increase in the relative abundance of the Ruminococcus gnavus group,Prevotella-9,Staphylococcus,and Actinomyces(P<.05).The functions of the both groups of microbiota primarily concentrate on metabolism,genetic information processing,and environmental information processing.The relative abundance of signaling molecules and interactions in the LS group were higher than that in the L group(P<.05).The redundancy analysis(RDA)showed that the URTI score had the greatest impact on the distribution of microbiota.Conclusion:GHRS may affect the development of URTI lung-heat syndrome by changing the relative abundances of gut microbiota.
